EXTENSION WINDOW-CORNICE.

SPECIFICATION forming part of Letters Patent No. 240,837, dated Mey e, 1881.

Application filed January 2G, 1881.

To all whom it may concern:

Be it known that I, JOHN MOORE, of Syracuse, Onondaga county, State of New York, have invented anew and useful Improvement in Extension I/Vindow-Cornices, of which the following is a specilication.

There have been several attempts to form extension-cornices for windows and like purposes, all of which, so far as I am informed, have lacked the elements of entire success.

By my mode of construction I cheaply form a stron g `and practical cornice. easily adj usted, and of perfect finish, expanding and contract ing to any desired degree.

The construction of' my improvement is described as follows, illustrated by the accom panying drawings, in which* Figure l is a view of the inner side of the cornice; Fig. 2, a crosssection ,-Fig. 3, perspective view ofinside ofcenter-piece detached Fig. 4, front view of the cornice.

The cornice may be made of any design in molding, as in Fig. 4, the front being divided at its center into two equal parts, c ct. Upon the back of one of these parts c two stout parallel bars, b b, are securely affixed, and proY ject over onto the other side an equal distance, the length of said bars determining the eXtension of the cornice. On-the inner edges ofthe bars bb are match-grooves, as distinctly shown in cross-section,Fig. 2. In the space between them a bar, c, fits and slides, having tongues on each edge to iit into the grooves in b b. This bar c is afxed to one of the parts a., and

(No model.)

the two parts c a are thus securely united, with freedom to be drawn out or contracted. The projecting ends of bars b b are firmly united by a brace, d, to resist the strain upon them caused by bar c, tending to pry them apart.

To cover the center space formed by drawing the side pieces, (t a, apart, I employ an ornamen tal cen ter-piece, c, ofany suitable design, and of sufficient length to lap over and cover the ends of pieces a c when the cornice is expanded as far as it is required. The inner face of this center-piece should conform to the molding against which it rests, and at its ends be covered with soft material ff to bear against and slide on the molding of the end pieces without chafingit. This center-piece is affixed in place by hooks or turn-buckles, to hold it properlyin place and allow it to be readily removed, as seen in section, Figs. 2 and Having thus fully described my invention, I claimp l. The combination of the end c having the bars b b affixed thereto with the end ct having the bar c afiixed to it, the bar c being jointed to and sliding between the bars b b, suhstantially in the manner and for the purposes specified.

2. The combination of the projecting bars b b and connecting-brace d, as and for the purpose specified. 4
